Abstract
The influence of two control methods on torque ripple in a three-phase switched reluctance (SR) motor is investigated using a ripple index based on peak speed fluctuations. Torque ripple is reduced by a current-tracking control method in which the desired stator currents are computed using a linearizing and decoupling transformation (LDT). At low speeds, even with an inexpensive switching amplifier, LDT control can reduce speed fluctuations by a factor of two. This may offer an advantage in direct-drive applications.
